To .all whom it may concern:

Be it known that I, JOSEPH G. HORA;-

povsiv, a citizen ofthe United States, residing at Cleveland, in the county of Cuyahoga Aand State of Ohio, have invented a certain f 4new and useful Improvement in Means for Operating and Locking Car-Doors, ofwhich the following is a full, clear, and exact description, reference beingA had to lthe accompanying drawings. v

My invention relates to means for operating and lockingcar' doors and'l has for its objects 'to 4provide such doors with sim le,

=poasitive and .effective ,y means whereby t iey may be opened and closed and to locate such operating means so ,thatthey will be inaccessible except from the roofs of the-cars with whichv they may be associated and to previde the same with lQking means which ositiv'ely lock thedoor. ii any desired posiien and which. be so located as( to make it necessary for the operator to get' onto the roof of the car in order to gain access to the lockV and to the operating means. n

is well known, the doors of frei ht cars are frequently opened by tramps an others for the purpose of steahng` a ride as Well as for the pur ose of removing the contents of the car. is particularly the case where the cars are collected in a yard, the doors of a great majority of the cars being invisible to the ivatchmen or the towermen. Even when the doors are provided with padloclrs, such locks are frequentlyT picked or broken.

'Vith the construction Whichwl have devised,

itwill be impossible for any person to open the doors of the cars without climbing upon the roofs of the cars, thereby placing themapplied thereto; Figs. 2 and 3 represent sec-v tional view's taken on the correspondinglynumberedlines ofv Figi, and Fig. 4 repref Y sents an enlarged perspective detail. show- 1 spaces between whlch are adapted to recelve 12 the roof thereof, and 3 the door.

ing the means whereby the door operating shaft is positively locked in any desired position of the door. y

Describing now the parts by reference characters,`1 represents the side of the car,

As illustrated, this door may be of the sliding t pe, being provided at the upper end with ro ers 4, carried by straps 5 and engaging a cleat or angle iron 6 on the upper portion ofthe car side and referably secured to the upper sill of thesi e traine. 7 denotes straps carried by the lower portion ofA the door and each provided with a roller 8` engaging an upwardly rojecting strip 9 carried by the lower s'1 4of the car frame.

To the inner surface of the door there is applied a longitudinally extending-rack 10, Said rack being Conveniently' formed l011. a metalli@ blf' Oi' 'Strip WhC'h .S Pivided Ifl'i-I one end with the lll-'shaped portion 11, by' means oi which' the rack may be bolted t( the door, leaving a space between the body ofthe rack and the door and betweenthe end 13 ofV the 'same and the door. The toothed portion of the bar extends beyond the edge of the door-and, when the door is in closed position, overlaps the 'side 1 of the car for a sufficiergtgdistance to receive there a pinion 13 mounted on an operating shaft 14.

The eperating shaft 14P has its lower end journaledin a suitable bearing 15 carried by the car'ioor and has its upper portion journaled in a suitable bearing 16 whichis carried by the up er sill 17 oi the cai-body frame. The upper en of the shaft projects through the roof and is' provided with an operating handle 18. To avoid interference with any of the articles that maybe stowed Within the car, shaft 14 and pinion 13 are incased'. The casing for pinion 13 is interposed between the sleeve sections ofv the casing for'the shaft is a ratchet wheel 22 said wheel being' pro- A l 1 i vided with square or rectangular teeth, the

the end ofa pawl 23, such end being shaped end of the pawl between a pair of teeth on the ratchet22.

The rack l may be conveniently located about midway of the height f -the'car door, '10 so that the lpower applied tothe rack may be exerted along. the vertical center of the door,

enabling it to be moved positivelybythe shaft and pinion, or a pairof such racks may be provided, one at the to and the other at l the bottom of the door, wit a pair of inions for ,operating the same, one for eac rack. For convenience of description, the end of the door adjacent to which the U- shaped portion 11 of the rack is bolted will be designated as the rear end of the door and the opposite portion will be designated as the front" end' 26 denotes a strap or plate which is carried by the upper rear end of the door and 27 a similar plate or strap which iscarried by upper portion ofthe side of the car, adjacent to the rear edge of the door opening.-

These plates or straps' are .provided respec-- ltively with apertures 28 and 29 at their upper 30 ends for the reception of a cord or chain 30 to whicha seal 31'may be applied.

` With the construction and arrangement of parts as described, it will be apparent that, in I order to'operate thejdoor, it l bie-necessary for the o erat'or to get on topof the car and remove t e locking end of pawl 23 from its ositionbetween the teeth of the `ratchet 22'. he operator-may accomplish such removal in any lwell known manner, as by pressing 40 his foot against the extension'24. When the door has been moved to adesired' osition, either open or closed or intermediatel between such positions, the lookin end of the pawl Will automatically enter-a recess in the .ratchet- 22. and 'automaticallylock the shaft, and, through its positive connection'with the door through the rack 10, 'theshaft will re-- tain door 3 in suchposition. 'lhe opposite ends of the rack bar 10,-,When the door is closed, assist in clamping the door to .the side o prevent the lateral displacement 0f .the

oor.

. It is a parent that I have embodied, inan extreme y simple construction, -means Whereby cardoors cannot be moved in directions to open or close the same Without the necessity for the operator to climb upon the roof of the car, thereby rendering'him extremely-liable to otservation bythe towermen', Watchmen, or other employees of the railroad. Furthermore, the arrangement of the lates 28and 29 furnishes `an indicatorwhere ythe-brakeman on top of. the'car can readily observe whether the door has been opened or tarn-y '65 peredwith.

.Having described my-invention, I claim 1. The combination, with a car., of aslid'- ing door therefor having a raclan operating shaft for saidv rack extending above the roof of the car and there provided with operating means, a pinion o n said shaft meshing with said rack, and locking meansv for said. shaft 'also located above "the roof of the car, substantially as specified.l
